Create Congress Nova datasource with api_version

The Congres Nova driver defaults to Nova API v2.0 but also supports
micro versions since Liberty release. This patch creates the Nova
datasource with the latest micro version available. This is useful for
scenarios such as invoking nova.services.force_down that was introduced
in v2.11.
